PRESS-WHEEL BOXING FOR GRAIN DRILLS.

Application filed February 12, 1926.

This invention relates to a wheel boxing construction for wheat or othergrain drills, and has for its primary object to provide such a boxingthat will prevent the passing of dust. dirt, and other foreign matterbetween the wheel supporting axle bars and housings therefor, whichwould otherwise impair the efficient operation of the press wheelsduring the movement of the drill over the ground.

Another and important object is the provision of such a wheel boxingthat may be readily disassembled for repair or renewal purposes.

Other objects will become apparent as the nature of the invention isbetter understood, the same comprises the novel form, combination andarrangement of parts hereinafter more fully described and shown in theaccompanying drawings and claimed.

In the drawing, wherein like reference characters indicate correspondingparts throughout the several views:

Figure 1 is a View in side elevation of a press wheel unit for graindrills constructed in accordance with the present invention, the samebeing shown as actually associated througlrmedium of a conventionalspring support through the usual grain drill gang press attachment bar.i

Fig. 2 is a detail longitudinal section thru a press wneel boxingconstructed in accordance with the present invention.

Fig. 3 is a view in end elevation of one of the axle housingelements,included as an element in the invention'.

Fig. 4 is a'similar view of the other axle housing section, and

Fig. 5 is a perspective of a bar secured at one end to the axle housingsection and at its opposite end to said conventional attaching spring.

Now having particular reference to the drawing, 5 indicates the usualhorizontal bar at the rear end of a Van Brunt or similar type of graindrill thru which the usual pairs of press wheels of a gang set areattached through medium of a conventional curvilinear band spring 6.

As is well known, a gang press for grain drills consists of a pluralityof press units, each unit consisting of a pair of assembled ress wheels,that are to be attached to said orizontal bar 5 of the drill. Forpurpose Serial No. 87,847.

of illustration, it is only necessary that one of these units comprisingthe gang be shown and described.

Such a unit consists of a pair of shaft housings 7 and 8 to be arrangedin end to end relation as clearly shown in Fig. 2, the adjacent ends ofthe sections being enlarged as at 7 and 8' respectively, the contactingfaces of which are formed with central circular depressions 9 withinwhich are arranged for free rotation, disks 1010 upon the inner ends ofwheel supporting shaft sections 1111 that are also freely rotatablewithin the housing sections 7 and 8.

, The outer ends of said shaft sections ll 11 are reduced in diameter asat 12-12 while mounted and secured thereon are the usual press wheels 13of the said unit, the inner ends of the hub portions 14-14 of said presswheels loosely engaging within sockets 15- 15formed upon the outer endsof the housing sections 7 and 8 to revent the passage of dust and otherforeign matter between v the shaft sections 1111 and said housingsections 7 and 8.

.One of the housing sections is formed at its top side with a laterallyextending circular lug 16 formed with a. threaded opening for receivingthe usual threaded nipple of a grease cup 17, said circular lug 16adapted to be arranged within a semicircular depression 18 at. the topside of the other housing section as clearly shown in Figs. 2 and 4.

The adjacent ends of .said housing sections are formed with a pluralityof radially disposed cars 19 that are formed with openings through whichsecuring means are adapted to be extended in order that the said housingsections may be rigidly interconnected. Also, each housing section isformed at its inner side and inner end with a forwardly extending andupwardly inclincd arm 20, that is formed throughout its length with adepression 21 for providing a socket for the inner end of a bar 22 whenthe housing sections are joined together, said arm and bar beingprovided with suitable openings as shown in order that the bar may besecured within the socket so provided. The forward end of the bar 22 isadapted to be connected in any desirable manner with the free end of thebefore mentioned curvilinear spring 6 that is secured at its oppositeend to the horizontal bar 5 over all conventional grain drills.

It will thus be seen that I have provided a highly novel, simple presswheel boxing for grain drills that may be readily lubricated and thatwill be substantially dustproof, thus permitting the drill to beoperated under all conditions, and that will not require the continualcleaning of the boxing that is now the case in other gang press units,and associated with grain drills.

Minor changes may be made in the invention without departing from thespirit and scope of the appended claims.

Having thus described my invention, what I claim as new is 1. In aboxing, a pair of complementary axle housing sections secured togetherat their inner ends, axles extending through the respective sections,press wheels on the outer ends of the axles, disks carried. by the inneropposed ends of the axles, the inner opposed faces of the housingsections having circular depressions formed therein in which said disksare rotatable, an apertured lug extending laterally from the inner endof one of the axle housing sections, the adjacent portion of the innerend of the other housing section being cut out to receive said lug, anda grease cup supported in the apertheir inner ends, axles extendingthrough the respective sections, press wheels on the outer ends of theaxles, disks carried by the inner opposed ends of the axles, the inneropposed faces of the housing sections hav-' ing circular depressionsformed therein in which said disks are rotatable, an apertured lugextending laterally from the inner end of one of the axle housingsections, the adjacent portion of the inner end of the other housingsection being cut out to receive said lug, a grease cup supported in theapertured lug and adapted to communicate with said circular depressions,means connected to the axle housing sections whereby the same may besecured to the supporting bar of a grain drill, said last mentionedmeans comprising a pair of complemei'itary arms PIOjBClZlXlg forwardlyfrom the inner opposed end portions of the axle housing sections, saidarms being formed with complementary depressons to provide a socket, andan attaching bar secured at one end within the socket.

In testimony whereof ll atfix my signature.

ANDREW M. STRECKER.
